Our Custom Non-Standard W75Cu25 Tungsten Copper Round Bars and Discs are precision-engineered to meet specialized customer dimensions, drawings, and high-stress application requirements. Manufactured through advanced powder metallurgy (pressing, high-temperature vacuum sintering, and copper infiltration), the W75Cu25 alloy (75% Tungsten, 25% Copper) offers high density, superior thermal arc resistance, and exceptional mechanical hardness coupled with high electrical conductivity.
These custom-machined short round bars and thick discs feature a fine surface finish, uniform microstructure, and precise dimensional control, making them ideal for EDM sparking electrodes, heat dissipation substrates, high-voltage arcing contacts, and resistance welding tooling.

Kungani Usikhethe:
1. Ungathola impahla ephelele ngokuvumelana nemfuneko yakho okungenani inani elingenzeka.
2. Siphinde sinikeze ama-Reworks, i-FOB, i-CFR, i-CIF, nezintengo zokudiliva umnyango nomnyango. Siphakamisa ukuthi wenze isivumelwano sokuthunyelwa okuzokonga kakhulu.
3. Izinto esizihlinzekayo zingaqinisekiswa ngokuphelele, kusukela kusitifiketi sokuhlolwa kwempahla engavuthiwe kuya esitatimendeni sobukhulu bokugcina.(Imibiko izovela ngokwemfuneko)
4. isiqinisekiso sokunikeza impendulo phakathi namahora angu-24(imvamisa ngehora elifanayo)
5. Ungathola ezinye izindlela zesitoko, ukulethwa komshini ngokunciphisa isikhathi sokukhiqiza.
6. Sizinikele ngokugcwele kumakhasimende ethu. Uma kungeke kwenzeke ukuhlangabezana nezidingo zakho ngemva kokuhlola zonke izinketho, ngeke sikudukise ngokwenza izithembiso ezingamanga ezizodala ubudlelwano obuhle namakhasimende.
